Jinsook Lee

I’m a Ph.D. candidate in Information Science at Cornell University. I’m co-advised by René F. Kizilcec in the Future of Learning Lab and Thorsten Joachims, with Nikhil Garg on the committee. I’m also fortunate to collaborate with National Tutoring Observatory, and AJ Alvero.

My research examines sociotechnical systems in education. My goal is to develop and evaluate responsible AI that supports an equitable society where future generations can thrive safely.

College Admissions and AI & Policy

I study how AI is reshaping the U.S. higher education system through diversity and equity perspectives. I examine (1) how post-SFFA policy has influenced diversity and arbitrariness in machine-driven decisions, and (2) the equity implications of generative AI in admissions, comparing pre- and post-GPT application essays across socio-economic groups. I ask what now counts as an "admissible" identity representation, how AI reshapes it, which populations become vulnerable, and ultimately what human values institutions should look for.

Improving Annotation Quality of Pedagogical Dialogue Acts

As part of the early studies at the National Tutoring Observatory, I apply technical approach to improve tutoring move annotation. I challenge the current utterance-level annotation unit and propose a segmentation method using LLMs and other dialogue-segmentation algorithms.

Measuring Relational Skills with AI Agents in hiring/workforce

I explore whether we can steer conversational agents to evaluate relational skills that are hard to discover from text-based applications in hiring and workforce contexts. I focus on capturing signals in simulated dialogue situations that require relational skills, and identifying which signals are most predictive of later performance.

Prior to Cornell, I spent several years as a data scientist at Korea University to develop course and major recommender systems to support college students’ decision making process.

I have a love-hate relationship with tennis — you’ll often find me attempting to upgrade my skills from the ‘absolute beginner’ category. I also love listening to music and curating songs!
